The Pyhton examples don’t manage to communicate with the BrickPi3.
Here what I have done:
- Flashed a micro SD with the experimental buster image for Pi4
- Booted and run
sudo apt upgrade
- Rebooted and run the DI Software Update
- Rebooted and tried to update the firmware, which failed, see Errors updating firmware Pi4+BrickPi3
- Run the examples for Python, see transcripts below, but got errors
pi@pi4:~/Dexter/BrickPi3/Software/Python/Examples $ sudo python Read_Info.py
No SPI response
pi@pi4:~/Dexter/BrickPi3/Software/Python/Examples $ sudo python Test_Connected.py
